createCsr
Creates a signed CSR from an attestable signer. Encodes the challenge's nonce into a KnownOIDs.serialNumber subjectName and the attestation statement into a Pkcs10CertificationRequestAttribute with AttestationChallenge.proofOID. Since this operation prepares and directly signs the CSR, it may require user authentication.
Parameters
The subject name, if required. Usually, you'll want to use pass AlternativeNames into additionalExtensions, not a subject name! By default, the RDN used for this CSR will only contain KnownOIDs.serialNumber containing the nonce from the passed challenge. Hence, the values passed to this parameter containing a KnownOIDs.serialNumber will be overwritten.
Certificate extensions to be requested. May be ignored by the issuer.
Additional CSR attributes to pack into this CSR.
